Abstract
A system (and method) assists consideration of selection that recommends selection candidates to a considerer who is considering selection in a certain field in order to assist determination of selection with which the considerer is satisfied. A question concerning the field is sent to a considerer and answer data is received from the considerer by the system. A degree-of-significance of each evaluation item in the field is estimated from the answer data. A degree-of-recommendation representing to which degree each selection candidate can be recommended to the considerer is calculated from evaluation data for each evaluation item with respect to each piece of selection candidate data in the field and the degree-of-significance of the considerer with respect to each evaluation item. Then, degrees of recommendation of selection candidate data in the field are presented to the considerer without change or after processing the data.
